WINDMILL MECHANISM.

SPECIFICATION forming part of Letters Patent No. 698,479, dated April 29, 1902. Appiitation filed April 19, 1901. seriaINo. 56,654. (No more.)

To all whom it may concern:

Beit known that I, MYRQN W. ELLIOTT, Jr. a citizen of the United States, residing at Beloit, Rock county, Wisconsin, have invented certain new and useful Improvements in Windmill Mechanism, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention has especial reference to the provision of improved means for braking the wheel, so as to stop the same from rotating when it is furled, and comprises novel devices for automatically accomplishing such result by {the relative' swinging movement of the wheel and vane.

A further object of my invention has reference to the provision of a novel formation of a guide for the pump-rod, the connection of the latter with the pitman which actuates it, and the support ofthe rod against the lateral stressesinducedby the angular-ity of the pitman when in operation,

The above, as well as such other objects as may hereinafterappear, I attain by means ofV a construction i which I have illustrated in preferred form in the accompanying drawings, in which- Y Figure 1 is a view in perspective, showing my improvement applied to a mill. Fig. 2 is a partial elevation or side view of the same'. Fig. 3 is an elevation on a plane at right angles to the plane of Fig. 2. Fig. et is a partial plan view of my improved mechanism. Fig. 5 shows a detail of the construction of brakerod and its connections. Fig. 6 is a View giving a detail of the pump-rod guidegand Fig. 7 is a horizontal section thereof, taken on the line 7 7 of Fig. 6.

Referring now more particularly to Fig. 1, it will be seen that upon the journal-casting 8, which carries the shaft of the wheel, there is mounted a wheel-hub 9, constructed so as to act as a brake-spider, adaptedto be engaged by a brake-ring 10, having a `slot 10 therein, which is longitudinally movable uponthejournal-casting Sand provided with a pair of lugs 11 upon each side of its hub 12, adapted to receive the yoke 13, which is fulcrumed at 14,' in a xed bracket 15, projecting upwardly from the casting 8 through the slotted opening 10, so as to prevent rotation of the brake-ring. The yoke 13 at its lower end is connected by means of a couple of. adjustingnuts 16 with a brake-rod 17, havingfpivotal some distance, as clearly shown in the drawings, and provided with aslotted opening 22, through which lthe crank-pin 23 forms connection between pump-rod 24: and the pitman 25, which actuates the rod. In forming the slot or opening 22 the metal of the tube which forms the pivot-pipe 21 is bent inwardly at each side of said slot, as clearly shown in Fig. 7, at 26, forming, together with the piece 27 and the inwardly-projecting flanges 28, a guideway for the pump-rod 24, so arranged y'as tohold the pump against lateral movement either away from the slot 22 or in a sidewise direction relative thereto. By this means the lateral stress due to the inclination of the pitman "25 is taken care of, the whole being formed at a low cost, because it involves the use of little material and is a construction very simple to make.

The operation of my brake mechanism is as follows: As the Vane-bar brace 19 is drawn out of gear or into a plane parallel with the face ofthe wheel, as is donewhen the mill is furled, it moves the brake-rod 17 in a direction to push the brake-ring 10 against the brake-spider formed in the hub 9 of the wheel, because of the engagement of the yoke 13 with the lugs 11 and the fulcrum-bracket 15 on the journal-casting 8, thus causing a stoppage ofthe rotation of the wheel. i If the brake parts wear or from some other cause itis desirable to regulate the amount of pressure between the brake-ring 10 and the hub 9, it can be readily done by properadjustment of the nuts 16 on the brake-rod 17. I

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An improvement in windmill mechanism comprising a journal-casting, a wheel-hub IOC constructed to act as a brake-spider, a brakering longitudinally movable upon said journal-casting, a lever for moving said brake- 4 ring, a fulcruin-bracket for said lever fixed relative to said journal-casting, and means for imparting movement to said lever when the mill is furled, said fulcrum-bracket preventing a rotation of the brake-ring Without a strain on said operating means, substan tially as described.

2. An improvement in Windmill mechanism comprising a journalcasting, a Wheel-hub constructed to act as a brake-spider, a brake- Wheel longitudinally movable upon said journal-castin g and provided With a collar having aslotted opening, a projection upon said journal-casting passing through said slotted opening to prevent rotation of said collar and brake-ring, and means operatively connected to said projection for impartinglongitudinal motion to said brake-ring, substantially as described.

pump-rod passing through said slot, and a guide for said pump-rod Within said pivotpipe formed by bending a portion of the Walls of the pipe inward, substantially as described. 4o
